What is a British Hallmark?
A hallmark provides important information about precious metal jewellery:
-
Who → The sponsor’s mark (the registered maker or company).
-
What → The fineness or purity mark, showing the precious metal content in parts per thousand.
-
Where → The Assay Office mark, showing which of the four UK Assay Offices (London, Birmingham, Sheffield, Edinburgh) tested and marked the piece.
-
When → A letter mark that represents the year of manufacture (this changes annually).
